Geotagged Picasa JSON/KML Output + Driving Directions = Instant Scenic Tours: If you were following the Google blogs yesterday, you would have heard that Picasa now gives you a sleek drag+drop interface for geotagging your photos, and that the Picasa Google data API now outputs the geotagged data using GeoRSS & GML elements. And if you were excited by all that news and immediately visited Picasa to try out the new feature, you might have noticed the big blue KML icon next to a "View in Google Earth" hyperlink. So Picasa now gives developers geotagged photo data both in KML output and the standard Google data API output formats, and that means we map developers have a lot of ways to start playing around with Picasa photos.
